The Cane Creek Thudbuster LT Suspension Seat Post is a high quality suspension seat post with impressive 3″ (76 mm) travel movement designed to improve seated-comfort when riding bicycles over rough terrain. Maximum rider weight 250 lbs, offers 142 mm to 346 mm extension travel depending on elastomer configuration, four elastomer weight ratings available that can be mixed and matched. Available in wide range of seat post diameters natively (eight total) including the most common 27.2 mm diameter, may be used with an optional shim accessory to fit even more. The post can slide down into the seat tube over time as body weight is applied, tightening the collar helps reduce this movement, due to the taller linkage sections of the Thudbuster Long Travel your saddle will not be able to mount as low as if you were using the Short Travel option or some other products.
